As shown in fig. 3, the display panel sealant coating method provided by the embodiment of the present invention includes:
and step S1, setting a starting point, an end point and a circular track of the path to be coated.
In this embodiment, the circular track of the path to be coated is related to the circular hole of the display panel, and according to the process and the specific requirements, the circular track may be as large as the circular hole of the display panel, or may be slightly larger than the circular hole of the display panel, for example, the radius of the circular track is 0.5 nm larger than the circular hole of the display panel.
